WRA-22...(A)

Fast running control ball valve consists of WRA-22.. series actuator and W8BV... series ball valve. Equal percentage flow characteristic guarantees the valve performances of stability. Stepping motor control ball valve. The characteristic of it is accurate,fast,strong anti-interference. It is a typical digital control mode.

They are widely used in HVAC system, heating system, water treatment equipment, and water running control in industrial automation, such as: AHU, flesh air-handling unit, differential pressure control unit and heat exchanger for flow regulation and on/off control.
